The championship's medical team has since ruled he is suffering from exhaustion.

It was originally suggested that this was the result of exhaust fumes coming into the cockpit after the race-two contact, but the team subsequently clarified that although this produced additional heat, no fumes entered the car.

Instead it believes the exhaustion was a legacy of Jordan's heavy crash on Saturday.

His absence means he will leave the meeting with just one point, his worst score since Oulton Park in June 2010, and leaves Jordan at least 63 points behind championship leader Colin Turkington.
